16.46.Q Thermo-Hygrograph
The Hygro-Thermograph measures and records both the relative humidity and the air temperature of the surrounding atmosphere. The recording drum is driven with utmost precision either by a manual spring clockwork mechanism or by a battery-operated quartz clockwork (see models available). Either H or K humidity measuring elements can be used depending on the general on-site operating conditions.
- H measuring elements are suitable for taking measurements in normal to very moist air at temperatures below and above 0°C.
- K measuring elements are designed for use in normal to dry air in the temperature range above 0°C and require no maintenance.
- Typical applications include environmental monitoring in computer rooms, factories, warehouses, offices, laboratories, nurseries, museums and galleries but they can also be used in meteorological measuring stations.
